Immunolocalization of ABA (green fluorescence) during senescence process of fine, absorptive roots. (A,B) Root control (RC); (C,D) The first stage of root senescence (RS1); (E,F) The second stage of root senescence (RS2). Autofluorescence (red) of the cell wall was registered in order to visualize the cell/organ shape. Abbreviations: R, rhizodermis; C, parenchyma cortex cells; Ct, cytoplasm; Ph, phloem, X, xylem. Scale bars = 50 µm.

Additional information:	ABA | Abscisic acid (C1) (for immunolocalization)
Additional information (application):	The antibody will recognize either the ABA conjugated to glucose ester (ABA-GE) or the ABA precursor: abscisic acid aldehyde, ABA aldehyde is however not usually present in plant tissue similarly to ABA alcohol which is also reactive, The antibodies will predominantly recognize only ABA and its glucosylester

Abscisic acid (ABA) is a plant hormone involved in different physiological responses as stimulation of the closure of stomata (water stress brings about an increase in ABA synthesis), iInhibition of shoot growth, and many others. ABA shown to have both inhibitory as well as many promoting functions.
